2. Public speaking

     Public speaking is the process or act of performing a speech to a live audience. Public speaking is commonly understood as formal, face-to-face, speaking of a single person to a group of listeners. However, due to the evolution of public speaking, it is modernly viewed as any form of speaking (formally and informally) between an audience and the speaker. Basically, it's a presentation that's given live before an audience. Traditionally, public speaking was considered as a part of the art of persuasion. The act can accomplish particular purposes – to inform, to persuade, and to entertain. Additionally, differing methods, structures, and rules can be utilized according to the speaking situation.

     Public speaking was developed in Rome and Greece. Prominent thinkers from these lands influenced the development and evolutionary history of public speaking. Currently, technology continues to transform the art of public speaking through newly available technology such as videoconferencing, multimedia presentations, and other nontraditional forms.    

     Public speeches can cover a wide variety of different topics. The goal of the speech may be to educate, entertain, or influence the listeners. Often, visual aids in the form of an electronic slideshow are used to supplement the speech and make it more interesting to the listeners.

     A public speaking presentation is different from an online presentation because the online presentation may be viewed and/or listened to at the viewer's convenience, while a public speech is typically limited to a specific time or place. Online presentations are often comprised of slideshows or pre-recorded videos of a speaker (including recordings of a live public speaking presentation).
